Rls-411ws - rings at night

[emi.hil_54193264062]

Hey,

I have two cameras rls-411ws and at night on each of them you can see such circles. One is the latest firmware, but nothing has improved.
Turning off the auto-focus and manual focus options does not help.

Is there any solution to this problem?

Hi Please contact our support team for replacing the faulty camera.

The cameras are operational. I have eliminated IR reflections. Information from https://networkcameratech.com/10-ways-to-improve-security-camera-night-vision helped me.
Thank you for your help.

Today's pictures. No other lights except IR LEDs in the cameras.
